[vlc-devel] [PATCH 00/12] Video integration within Qt interface for Windows

[Pierre Lamot]

This branch allow integrating the video within the Qt interface on Windows using
DirectComposition

This should work on Windows 8+ (and fallback on a separate window for former
versions of windows)

Video is rendered in the DComp tree by specifying a new window type (DCOMP) and
rendering to the DComp visual directly from the d3d11 module (using a
specialized swapchain)

The UI is rendered to a framebuffer using ANGLE interop, then rendered within
DComp tree using a custom swapchain.

QML components have been separated from the main interface allowing us to have
control over its rendering.

Now qt module starts by instantiating a Compositor which have the
responsibility of:

- create the main window
- setup the UI within the main window
- create/setup the video window/surface

Note that this branch currently don't compile as-is on GCC CI as the MingW
headers (dcomp.h) provided in the docker are outdated. Should compile fine
on Clang CI though.

branch is available at https://code.videolan.org/chub/vlc/-/tree/dcomp/10

Pierre Lamot (12):
  d3d11: allow rendering video to DirectComposition surfaces
  qml: rename rootWindow to mainInterface
  qml: use the top window to filter global key events rather than the
    embed widget
  qt: remove dependency from mainUI in the toolbar editor
  qt: move vout window report functions to the Video surface provider
  qt: add compositor interface
  qt: provide a dummy compositor
  contrib: remove dllimport from ANGLE EGL api
  qt: add DirectCompositor compositor
  qt: move qml initialisation out of the main interface
  qt: remove qml instantiation and video embedding from the
    main_interface
  qml: fullscreen button should ask videofullscreen
